mean square error

基本解釋

However, two-stage estimates of regression coefficients corresponding to these two estimates have approximate equal mean square error.
對應于方差參數這兩種估計的回歸系數的兩種兩步估計，它們的均方誤差大致相當。
Both channel and echo response can be shortened at random with a single FIR equalizer by following the minimum mean square error rule.
使用最小均方誤差準則，用一個FIR均衡器聯合縮短信息與回波沖激響應，有效地縮短了回波和信道沖激響應長度。
In comparison with traditional LMS algorithm, WO-LMS algorithm can achieve both lower steady mean square error and faster convergence speed.
與傳統(tǒng)的LMS算法相比，WO-LMS算法既提高了收斂速度又可以得到較低的穩(wěn)態(tài)均方誤差。
